Effects of weak connecting structure on penetration performance of free-flight rocket

Abstract The strength of connection between the rocket engine and warhead has a certain relationship with warhead’s ballistic characteristics structural response. In this paper, effects weak connecting structure on penetration performance free-flight (unguided) rockets is studied by numerical simulation experiment. oblique different structures into armour plates numerically simulated, rockets’ deflection in process analysed, integrity are evaluated according to deformation tail. test designed, results under low impact velocities verified. research shows that influence length tail varies at velocities. It better use direct high velocities, performs
